So, yesterday, on Pojo Forums (where there is an area for “RMT's”, similar to those of Smogon's), were, I encountered one team that utilizes a Metal Burst Aggron set, and it is one I have not encountered before, and, as such, it piqued my interest. The exact set, is as such:
Aggron @ Full Incense
Trait: Sturdy
EVs: 252 Atk / 252 HP / 4 Def
Brave Nature
- Metal Burst
- Stone Edge
- Iron Tail
- Earthquake
I'd imagine most know the standard Wish Chansey set, so I won't add that. Since Wish Chansey can heal massively (and I'm not sure, but I think it can completely heal Aggron), thus greating increasing Aggron's longetivity and to continue to put out consistent Metal Bursts without much worry.
So, my exact question is if this is viable in the OU tier (and potentially any other tier in competitive battling where the combination can be legally used).
